Answer:
Graph Y is the correct answer
Step-by-step explanation:
after 1 year, the price would be $200 * 1.15 = $230
After 2 years, the price would be $230 * 1.25 = $264.5
As you can see, the graph X and Z do not start at $200 in the first year so it will be eliminated
The graph W show that after 2 years the price is $300 but the second year must have the price of $264.5 so the only option left is graph Y.
Hope this can help!
Answer:
sln
3b-2a=7
3b-7=2a(divide by 2 both sides)
a=3b-7/2
my second opinion would be you are correct, its b
15) factor out cos: cos(x)(sin(x)+1)=0
Now this is true when either cos(x)=0 (x=pi/2 and 3pi/2)
Or when sin(x)=-1 (x=3pi/2)
So it's solutions are pi/2 and 3pi/2
